SIXEL to XBM Converter
Processing entirely on your device — large files may take a moment.
DEC SIXEL Graphics and X BitMap exist for different jobs: SIXEL is DEC's terminal graphics protocol — raster images rendered inline in VT340/xterm terminals, revived by modern terminal emulators for image display over SSH. Convert XBM icons to PNG for viewing, or emit XBM when embedded firmware/Unix code needs a compiled-in bitmap.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.
How SIXEL compares to XBM
| SIXEL | XBM | |
|---|---|---|
| Structure | DEC SIXEL Graphics coder | C #defines + hex byte array |
| Compatibility | ImageMagick, specialty tools | X11, C compilers, GTK |
| Best for | Legacy and specialty pipelines | Compiled-in cursors and icons |

About the SIXEL format
The DEC SIXEL Graphics coder of the ImageMagick set — the terminal-graphics format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing
About the XBM format
XBM is the most honest image format ever shipped: the "file" is a C source array of hex bytes, compiled straight into X11 applications as cursor and icon bitmaps. Rendered, it is 1-bit black and white — the ancestors of every pixel-art cursor you still use.
Because it compiles, XBM never died: firmware UIs, embedded icons and retro Unix tooling still want it. Converting a PNG down to XBM gives embeddable, compilable art; the other direction previews what the C array actually draws.
+Strengths
- ✓Compiles directly into C/C++ programs
- ✓Zero-payload format — text only
- ✓Still required by embedded and Unix tooling
!Limitations
- −1-bit black & white only
- −Human-hostile representation
- −X11 bit order trips up hand-rolled decoders
Why convert SIXEL to XBM?
Think of it as moving your file to the container that fits the job. Niche format — few modern readers XBM works differently: Compiles directly into C/C++ programs If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this SIXEL to XBM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting SIXEL to XBM?
No — XBM is a lossless format, so every pixel of the converted image matches your original SIXEL file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your SIXEL files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Can I convert several SIXEL files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
